Maternal serum levels of estriol, prolactin, human placental lactogen and chorionic gonadotrophin related to fetal sex in normal and abnormal pregnancies.
A total of 222 pregnant women had repeated hormone assays of prolactin, estriol, human chorionic gonadotrophin and placental lactogen between week 20 and delivery. The aim of this study was to investigate whether maternal serum levels of the above-mentioned hormones differed between normal and abnormal pregnancies, that is preterm, preterm small-for-date (SFD), SFD at-term and normal at-term deliveries, with special regard to fetal sex. The results of the present study indicated differences related to preterm deliveries and intrauterine growth retardation. This finding was reflected in the estriol levels when mothers of both boys and girls were included, suggesting a primary involvement of fetoplacental factors in these pathological pregnancies. However, when only mothers of girls were investigated, the development of growth retardation was mainly seen in maternal serum hPL differences, thus suggesting a placental involvement.
